Am I correct that if I have my AutoChart ZeroLine card in my Helix G2 and turned AutoChart recording on, that there is no need to record tracks or sonar to the card also? That all that information is already being updated on the ZeroLine card as I record? That would mean the main purpose of AutoChartPC would be for manipulation or converting sonar recordings & tracks from other recordings from my other 999 to AutoChart Data files to export to my AutoChart ZeroLines card?
